Woods is right on point. Long Island Indicator Service has an outstanding website that goes into good detail about all kinds of instruments. Their customer support is excellent and received mine within several days. Here's the link to the pair of calipers I purchased from them and haven't looked back. To some may be pricey but worth every penny. I like to have confidence in the tools I use, after all safety is at hand.

Starrett dial calipers have a marked disadvantage. The metal is soft and bends easily under heavy use. The jaws quickly become misaligned and errors appear. Plastic parts have shown up on recent models and no one is impressed. It is not clear where these are manufactured, but Starrett would like you to believe it's here in the States. One model of 6" calipers (1202A) is clearly made in China (but made of harder steel, so it's actually a better gage). Buy Starrett for the name but not for the quality. The crystal and bezel assembly can be purchased and installed without much trouble if you ever need to replace the plastic lens.
